The main components of the NFC tag issuing apparatus and the connection relationship thereof are described above, and the following describes the NFC tag issuing method.

Fig. 5 is a flowchart of an issuing method of an NFC tag according to an embodiment of the present invention, where, as shown in fig. 5, the issuing method of an NFC tag according to an embodiment of the present invention includes one or more issuing processes, and the issuing process mainly includes the following steps:

step 110, the label paper driving structure receives an issuing signal sent by an issuing system, drives a label paper installer to rotate according to a preset rotating speed, and further transmits Near Field Communication (NFC) label paper to be issued, which is installed on the label paper installer, to a label issuing assembly;

specifically, the label paper driving structure may be a torsion stepper motor. The issuing system may specifically include a power controller and issuing software that may be installed on a touch screen display control, such as within an android device. The power controller adopts MCU digital control technology to realize complex motion control such as slow acceleration, slow deceleration, quick stop, electromagnetic braking, etc. The tension of the NFC label paper is adjusted through the power controller, so that the NFC label paper is stably transmitted to the issuing panel. Various parameters in the issuing process, such as equipment parameters and issuing label parameters, can be set through the touch screen display control end. The equipment parameters specifically comprise: tag installer rotational speed, operating time, sensor parameters, NFC reader parameters, etc. The issuing tag parameters specifically include: label issuing rate, label diameter, label thickness, number of issues, etc.

In a specific example, the preset rotating speed of the label installer is 50-100 cm/min, the label issuing speed is 1.2 seconds/piece, the maximum sensing speed of the sensor is 1 millisecond/piece, and the reading and writing speed of the reader is 1.1 seconds/piece.

Step 120, the tag sensing component generates a position matching signal according to the collected positioning information of the NFC tag on the tag issuing component, and sends the position matching signal to the issuing system;

specifically, in this example, detection and approval of the tag position information is performed by the first sensor, i.e., the chip sensor, and the second sensor, i.e., the color sensor. Position matching can be understood as the working position of the tag already in the read-write area. And finally, the position matching signal is sent to release software of the touch screen display control terminal.

Step 130, the issuing system sends first tag data to the tag issuing component according to the position matching signal;

specifically, the issuing software of the touch screen display control end only sends the first tag data to the NFC reader-writer in the tag issuing component when receiving the position matching signal, so that the matching of the tag issuing rate and the reading and writing rate of the reader-writer can be ensured. The first tag data may be understood as data encrypted after associating the product information with the tag data.

Step 140, the tag issuing component writes the first tag data into the NFC tag, generates second tag data, and sends the second tag data to the issuing system;

specifically, it can be understood that the first tag data is theoretically the same as the second tag data, but is affected by factors such as signal interference when the data is written, so that the issuing system is required to verify the data written by the NFC reader-writer, and accuracy of the NFC tag information is ensured.

Step 150, the issuing system verifies the second tag data;

specifically, the issuing system compares the first tag data with the second tag data, and executes step 160 when the verification passes, and executes step 170 when the verification fails.

Step 160, when the verification is passed, generating NFC label issue success information;

specifically, the issuing system may continue the next issuing process according to the NFC tag issuing success information.

In step 170, when the verification fails, NFC tag issuance failure information is generated, and the NFC tag issuance failure information is sent to the label printing component, so that the label printing component marks the NFC tag that fails to issue.

Specifically, the verification failure may be understood that the second tag data is inconsistent with the first tag data, that is, the first tag data is wrongly written or failed, and the corresponding NFC tag is a bad tag or a wrong tag. From this, this issue device is through simple structure, convenient operation, has both realized the automatic transmission of NFC label, data write-in, has checked and recorded, has improved NFC label's release efficiency, can also improve NFC label's quality, avoids problem label entering market, reduces NFC label's anti-fake effect.

In a preferred scheme, the issuing method can also realize batch binding of the two-dimension codes and the labels. The specific process is as follows:

firstly, a two-dimensional code acquisition part acquires two-dimensional code data information on an NFC label and sends the two-dimensional code data information to an issuing system;

and secondly, the issuing system correlates the label information of the NFC label with the two-dimensional code data information according to the two-dimensional code data information, so that batch binding of the two-dimensional code and the label is realized, and the problem of poor anti-counterfeiting effect caused by independent operation of the two-dimensional code and the NFC label subsystem in the prior art is solved.
